The much-anticipated first person non-shooter Mirror's Edge is being released today for the Xbox 360 and Playstation 3. Reviews for the game, while not without complaints, are generally positive. 1Up praises the controls, saying, "It gets things very right very early, distilling its first-person platformer ambitions into a very manageable control scheme. ... Once you're familiar with Faith's abilities and their limitations — imparted through a much-needed tutorial — it's easy to see potential routes through the world." Ars Technica is more critical, noting that the main story's gameplay only clocks in at about six hours, and that the artistic style doesn't vary much between levels. Nick Channon, a producer for Mirror's Edge, sat down with Gamasutra and discussed the reasoning for some of their design choices. The PC version of Mirror's Edge and some additional downloadable content will be available in January.

A study has found that everybody has a unique body odor, like their fingerprints, that could be used as an unique identifier. The study showed that a persons unique odor stayed the same even if they varied their diet with strong smelling foods such as garlic and spices. "These findings indicate that biologically-based odorprints, like fingerprints, could be a reliable way to identify individuals," said Monell chemist Jae Kwak. I would have thought that hundreds of years of dogs tracking people would have proved this, but it's nice to know that science has figured it out officially now.
